Be it knownthat 1, WILLIAM ANDERSON, photographer, residingat 36-;Hamilton Bflace, Iartick, in the ciiyof Glasgow, Scotland, have 5invented a v ignetting Machine to Vignette Pboiographsfior which I haveobtained a patent in Great Britain,No. 20,2ai3, hearing date September24, 1898,) of which th'eiollowing is a specification.

l0 lily-invention has for its-object, to provide asimple,cheap, andefiicient machine to sign ette photographs. f

Incarryingout my invention I provide a spindle of any convenient length,which rests 'igjo'n a suitable standard, and fixed to" the end of thespindle is a box for holding-the print ing-frame. This box is providedwith a cover, on which tissuepaper, cheesecloth, or fine muslin isstretched togire diliusion or" light so to maizesoft vignettes.-

' l have shown my invention in the accompanying drawings, in which-- VFigure 1 is a perspective View of one form of my invention. Fig. 2is aperspective View of a'modified form of same. Referring to the drawings,A is a spindle, which is suitably mon'nted. on a stand'ardB. To one endof the spindleis fixed the box 0 forholding tho printing-frame, andair-the opge posite end thereof is secured ahandlo D for turning thespindle, and thereby rotating the box, The box 'Clsreotanghlarinshapeand "providedwith a removable cap or cover E, upon which isstretched tissue-paper,cheese cloth, or fine xnuslin,"or a combinationof his suepaper and cloth, to give the required diffusion. of light. Inthe side of the box is an opening F, through which the printing-framecontaining the negative may be inserted, no Pivoted to thebox at oneside of theiopening is a bar or latch G, which is adapted to be placedacross the opening and have its free end caught in a suitable catch onthe oppo site side of the opening, thereby preventing the frame fromfalling out of the box.

' The device or box is placed opposite a lamp, gas-burner,'or otherlight and rotated by turning the'handlc, in Fig. 2 l have shown thespindle supported on two arms K K, which, are fixed to a base late L, inwhich a longitudinal slot M is formed. In this slot a lamp N, having aregulator 92, is slidingly secured. The surface of the base L is markedwith a scale, so that the operator can without difficulty regulate thedistance between the. lamp and the box. and ascertain same at all times.A table takes the place of the standard B in this adaptation of myinvention; If a gasjet be employed, the lamp may be connected with thesource of gas-supply bya suitable flexible tube, as shown in Fig.

Havingthus described my invention, what claim as new, and desiretoobtain by Letters Patent, is-- 1. A vignetting machine composed .of asuitably-mounted spindle, a box mounted on said spindle adapted tohold'a printing-frame, and provided with a cover formed of tissuepaperand cloth, and means for securing a frame within the box, substantiallyas set forth. w
